3. Zero VOC & Low VOC
According to EPA (Environmental Protection
Agency) standard
• Technically, the term “zero VOC” paint applies
to paints that have < 5 g/L of VOC.
• The term “low VOC” paint has been applied to
paints having a wide range of VOCs from 30
g/L to as much as 250 g/L

7. What BASF can offer
Acronal ECO binders
• Definitions of Acronal ECO range
– Low Odour
– Low VOC’s
– APEO surfactant free
– Formaldehyde Free
– Ammonia Free
• BASF’s advanced production technology makes Acronal ECO
almost free of VOCs and odour causing chemicals without
affecting the functional properties.

8. BASF Deodorization Technology
Acronal® ECO
• All odour and VOC
causing impurities are
Acronal® ECO removed by BASF
special deodorization
Technology
• Most Properties of
the new dispersion
remain the same
giving NO compromise
Conventional
on properties of a
paint
Acronal® Dispersion
Many years of Basic Fundamental Chemical and Engineering Research
has made BASF a pioneer in this technology

14. Driving force for Low/zero VOC paint
Pushes of low/zero VOC However, there is No
paint to consumers strong consumer pull!
come from
• Consumers don’t
• Legislation/government understand VOC
• Industry itself Low VOC paint • Consumers don’t see
Zero VOC paint benefits from low VOC
• Competition
and are not willing to
pay a higher price

39. Summary
• ECO products give Low VOC, low odour to the
paint along with added properties
• Replacing synthetic enamel by acrylic or
Alkyd/acrylic hybrid would give better
durability
• Better durability leads to longer paint life
cycle.

43. Water based paint for gloss
enamel
Options for 2011
• Alternatives to solvent based alkyds
• high solids (solvent based alkyds)
– “alkyd like” (familiar) rheology
– still significant solvent level needed
(not “really green”)
– difficult to achieve for tinted systems
(coloured pigment distribution)
01/02/2011
44. Water based paint for gloss
enamel
Options for 2011
• Alternatives to solvent based alkyds
– water based alkyds
– no major change in chemistry (film properties)
– no technical selling point vs. solvent based alkyds
• “typical“ alkyd problems, such as
yellowing, bad weathering performance
01/02/2011
45. Water based paint for gloss
enamel
Options for 2011
• Alternatives to solvent based alkyds
– water based acrylics
• acrylic benefits (weatherability, whiteness)
• limited gloss level
01/02/2011
46. Water based paint for gloss
enamel
Options for 2011
• Alternatives to solvent based alkyds
– water based PUs
• good surface characteristics (chemical resistance)
• expensive
• limitations in achievable gloss level
01/02/2011
47. Water based paint for gloss
enamel
Options for 2011
• Alternatives to solvent based alkyds
– Polymer blends
• combine benefits and deficiencies of different systems
• need cobalt siccatives
